Web sites need passive and active SEO. Tad Chef defines both before providing a detailed example to support his thesis. He writes that passive SEO is when you create a resource once and then gain long-term traffic and sales on the Web site with little effort. It works on "autopilot." Active SEO requires you to continually create content or build links for content on blogs or Websites.
Chef provides insight on finding topics to write about for blog posts and Web site content. He suggests checking search analytics for questions that get asked repeatedly, as well as well as look for unanswered questions on forums or Q&A sites. Answer the question with a resource that offers answers and leads to a solution sold by your company, he writes.
